Set material with Anisotropic BH curves

[codychan2231]

Does anyone have experience setting the material with anisotropic BH curves?
I have no problem setting the permeability for nonlinear type with the below setting. However, when I need to make it anisotropic and set T[1,1], T[2,2], and T[3,3] with [bh_points1, bh_points2, bh_points3], the aedt doesn't work.

I tried m2d.materials.permeability=[1,1,1], the aedt would set the material into Anisotropic, but I need each of them to be nonlinear and assign specific BH curves.

bh_points = [
[0, 0],
[140, .85],
[200, 1.013],
[300, 1.185],
[400, 1.273],
[600, 1.36]]

m2d.materials.permeability= bh_points

Hi @codychan2231 ,

You missed specifying to which material you want to define this property:

from ansys.aedt.core import Maxwell3d

app = Maxwell3d(version="2025.2")

mymat = app.materials.add_material("new_mat")

mymat.permeability = [
    [0, 0],
    [140, .85],
    [200, 1.013],
    [300, 1.185],
    [400, 1.273],
    [600, 1.36]]

app.materials["new_mat"].permeability = [
    [0, 0],
    [140, .85],
    [200, 1.013],
    [300, 1.185],
    [400, 1.273],
    [600, 1.36]]

My program did put the material name. It was my fault that did not type it in the question.
However, I am sure the pyaedt is not be able to set anisotropic by giving .permeability=[bh_points1, bh_points2, bh_points3].

One of my friend suggest me to use oDefinitionManager by recording the script that I set the anisotropic manually and this method does work. I don't know if it's because I am using 2024.2 or why?

I have tested it again 2025R1, and it worked:

Please could you try the snipped code?

I do not have 2024R2 installed.

Hi Samuel, the function you showed me is working in my computer as well, but I need the T[1,1] and T[2,2] to be set.
